Jazz Pharmaceuticals (NASDAQ: JAZZ) has achieved a groundbreaking milestone with the FDA's accelerated approval of Modeyso™ (dordaviprone), the first-ever treatment for H3 K27M-mutant diffuse midline glioma with progressive disease. This ultra-rare and aggressive brain tumor affects approximately 2,000 people annually in the U.S., primarily children and young adults.

The approval is based on clinical studies showing an overall response rate of 22% among 50 patients, with a median response duration of 10.3 months. Among responders, 73% maintained their response for at least six months. The safety evaluation, conducted across 376 patients, revealed serious adverse reactions in 33% of cases.

Modeyso, administered as a weekly oral capsule, will be commercially available in the coming weeks. Continued approval may depend on results from the Phase 3 ACTION confirmatory trial.

Jazz Pharmaceuticals (Nasdaq: JAZZ) has received conditional marketing authorization from the European Commission for Ziihera® (zanidatamab) for treating adults with unresectable locally advanced or metastatic HER2-positive (IHC 3+) biliary tract cancer (BTC) who have received at least one prior line of systemic therapy.

The approval is based on the Phase 2b HERIZON-BTC-01 trial results, which demonstrated significant efficacy in the largest study conducted to date in this population. Key findings include:

• Confirmed objective response rate (cORR) of 41.3% in the overall population
• Higher cORR of 51.6% in IHC 3+ tumor patients
• Median duration of response of 14.9 months
• Median overall survival of 18.1 months in IHC 3+ patients

Ziihera becomes the first HER2-targeted therapy authorized for HER2-positive BTC in the European Union. The approval extends to all EU Member States, Iceland, Norway, and Liechtenstein. Continued approval is contingent upon verification of clinical benefit in the ongoing Phase 3 HERIZON-BTC-302 trial.

Jazz Pharmaceuticals announced FDA Priority Review acceptance for Zepzelca in combination with atezolizumab as first-line maintenance treatment for extensive-stage small cell lung cancer (ES-SCLC). The FDA set a PDUFA date of October 7, 2025. The application is supported by Phase 3 IMforte trial results, which showed significant improvements in both progression-free survival (5.4 vs 2.1 months) and overall survival (13.2 vs 10.6 months) compared to atezolizumab alone. The combination reduced disease progression/death risk by 46% and death risk by 27%. The treatment showed no new safety concerns and could provide a crucial new option for ES-SCLC patients, addressing a significant unmet medical need.

Jazz Pharmaceuticals (JAZZ) presented Phase 4 data for Xywav at SLEEP 2025, showcasing positive outcomes in narcolepsy treatment. The XYLO switch study demonstrated significant blood pressure reductions when patients switched from high-sodium to low-sodium oxybate, with a -4.1 mmHg change in 24-hour systolic blood pressure (P=0.0019). The study met its primary endpoint and key secondary endpoints, including improvements in daytime and resting blood pressure. Additionally, the DUET trial analysis showed effectiveness of Xywav at 9-12g doses, higher than the currently recommended 6-9g, with improvements in excessive daytime sleepiness. Both studies reported only mild to moderate treatment-emergent adverse events, consistent with Xywav's known safety profile. Xywav remains the only FDA-approved low-sodium oxybate for treating narcolepsy and idiopathic hypersomnia.

Jazz Pharmaceuticals announced breakthrough results from their Phase 3 IMforte study, showing Zepzelca (lurbinectedin) combined with atezolizumab significantly improved survival in extensive-stage small cell lung cancer (ES-SCLC) patients. The combination therapy, used as first-line maintenance treatment, reduced disease progression or death risk by 46% and demonstrated median overall survival of 13.2 months versus 10.6 months for atezolizumab alone. The study met both primary endpoints with statistically significant improvements in progression-free survival (5.4 vs 2.1 months) and overall survival. The combination therapy showed a manageable safety profile with no new safety signals, though it had higher treatment-related adverse events (83.5% vs 40.0%). This groundbreaking study is the first Phase 3 trial to show meaningful improvements in both progression-free and overall survival in ES-SCLC first-line maintenance, potentially establishing a new standard of care for patients.
